I've had Slay on the iPhone for a long while now. Love it, but haven't finished it yet. I'm buying an iPad this weekend, and wondering if there's a way to sync my progress between the iPhone and iPad? Maybe something built into GameCenter or using Dropbox?

It'd really be nice to transfer my progress over to my iPad, and in the future be able to go back and forth between my two devices, and have any completed maps show up on both units.
